Reproduce “Switch” Functionality

Problem

You want to do something like this ExpressionEngine statement, using Twig:

{switch="<tr>|||"}

Solution

There are two possible solutions: divisible, and cycle.

{# Using `divisible` #}
{% if loop.index0 is divisible by(4) %}
    <tr>
{% endif %}

{# Using `cycle` #}
{{ cycle(['<tr>','','',''],loop.index0)|raw }}
